PHYSICAL SCIENCE PAPER 1 SECTION A foreland 1: ONE-WORD/TERM ITEMS Give ONE cry/ bourn for EACH of the following descriptions. Write only the vocalize/ end point next to the question tot up (1.1 1.5). 1.1 1.2 1.3 1.4 The minimum amount of zilch required to remove an negatron from a metal go up (1) The energy of a body due to state of cause (1) The bending of take up when it enters an optic everyy more dense medium (1) The product of the magnetised field strength inside a single curve of conductor and the argona enclosed by the coil (1) 1.5 increases the capacitance of a capacitance when placed between the reduplicate plates of the capacitor (1)[5] school principal 2: CORRECTING FALSE STATEMENTS The statements in questions 2.1 2.5 are FALSE. Correct the statements. 2.1 When you hold a 1 kg toilet in your surpass with your palm facing upwards, the response to the free weight of the 1 kg mass is the normal line of the hand on the 1 kg mass. (2) 2.2 The refractio n and diffraction of light two involve light bending when it passes into an optic all(prenominal)y denser medium. (2) 2.3 If devil undergrounds of 3 ? and 5 ? respectively are connected in parallel in a closed circuit (charge is menstruum in it), the potential difference crossways the 3 ? resistor entrust be higher than the potential difference across the 5 ? resistor. (2) 2.

4 For the lasing process to be initiated in a laser, all electrons in the laser material must be in higher electron energy levels. (2) 2.5 The oscillatelength of a matter revolve the waves associated with moving particles is proportiona l to the momentum of the particle. (This sec! tion is not examinable.) (2) [10] gesture 3: MULTIPLE-CHOICE QUESTIONS Four possible answers are provided for on an individual basis of the following questions. Choose the correct answer and make a cross (X) in the block (A D) next to the question come up (3.1 3.5). Each question has ONE correct answer. 3.1 Two trolleys, A (2 kg) and B (4 kg), stand on a frictionless, horizontal give over top. They are connected by a arctic band. The two...If you regard to get a full essay, order it on our website: OrderCustomPaper.com
